Why does battery import from grid?

[max99]

Question is why is Solis inverter importing energy from the grid when the battery is 77% full?
Normal charge time is between 00:00 and 4:00am
Over Discharge is: 20%
Force charge is: 15%
Battery is 4.8kWh Phylontech Phylon US5000
Solis inverter 3kW
SOL-3K-RHI-4BES-%G-DC hybrid 5G inverter

Just seen your message - is this still an issue. If so a screenshot of the Solis screen would be helpful.

Here is example of import and below is example of export

It's difficult for an inverter to hit exactly 0 watts considering L1 and L2 are going to have some imbalance.
40 and 60 watts isn't much energy.

40 and 60 watts isn't much energy.

We won't go down the discussion that Watts is power, Watts per second is energy ... but...

a) see what the Solis screen shows on the inverter itself - the solis app is a bit dodgy and
b) ignore anything under 100W... when there is no PV input the Solis will draw 30W from battery just to power itself.

Thanks!
I meant 40/60 watts over time ?
